Q400 costs
Several years ago, each US Airways wholly owned regional company was tasked with doing cost analysis on the current RJs being manufactured. In addition to these surveys, one of the WOs, I believe ALG, did a presentation to U management on the viability of a Q400. Dollar per dollar, the Q400 could operate in their enviroment (NE Corridor) less than the CRJ and ERJ, but the cost difference wasn't substantial...not the "golly gee wiz" stuff they where looking for. Also, per aircraft, the price difference from the CRJ (which is what PSA got) wasn't that much different, either.
Wolfe and Gangwal were bent on RJ expansion at the least amount of $$$ at the cheapest bidder. The result is what you see now. The Q400 analysis was treated as a "thanks, but no thanks" idea. With fuel prices now soaring, it is apparent that DS and the folks in Crystal City are rethinking this idea.
The Horizon guys could give better feed back. I was able to visit the Q400 sims in SEA and YYZ and play. The cockpit is huge, like the current DASH fleet aircraft (Boeing original design?), less that 12" diameter trim wheel on either side of the pedestal. Flight Safety SEA had a press release in the break room that stated the Q400, with its PW150s (5000 shp) had broken the time to climb record for turboprops, climbing from SL to FL180 in, I think, 7 minutes. Pretty good for a prop airplane. Last I heard, it was still a common Type.
As for U, someone has to finance any order; U has no $$$. I wonder if Bombardier will come through with a deal like Tolouse did....
